Summary:
In a dystopian near-future version of Gotham City, a 55-Year-Old Bruce
Wayne has retired from being Batman following the death of his former
Robin, Jason Todd. Criminals now run amok and the city is constantly
terrorized by a gang known as the Mutants. Bruce Wayne is now something
of a recluse, despite his continuous philanthropic endeavors and
friendship with Commissioner James Gordon, who now knows Bruce's former
identity as Batman.
